A transformer is to be designed to increase the 30-kV (rms)output of a generator to the transmission line voltage of 345 kV (rms).If the primary winding has 80 turns,how many turns must the secondary have?
A)6
B)70
C)920
D)9 200

The transformer turns ratio is given by the formula: $ \frac{V_s}{V_p} = \frac{N_s}{N_p} $. Here, $ V_s = 345 $ kV, $ V_p = 30 $ kV, and $ N_p = 80 $. Solving for $ N_s $, we get $ N_s = \frac{345}{30} \times 80 = 920 $ turns.
